Well check out SVBs most recent 10-Q. Everyone knows they had $90B in MBS but most people haven’t commented on the fact that they also had $70B in loans as part of their assets. Normally loans are considered pretty safe assets, but as others have commented a good part of these loans are to the same depositors (startups) that SVB owes money to. Additionally SVB lent money to founders to buy homes, cars, etc. Hopefully you can see where this is going now… The real question is going to be how much if any of those loans SVB can recover to cover their deposits. This could mean calling in all kinds of credit instruments from startups that are ill prepared to suddenly pay them back.
Unless the loans are forgiven, in addition to making the depositors whole, SVB will still take a whole bunch of startups down with it. Those companies vendors will feel the hit too. It may take some time for the full repercussions to be felt but this is going to be a big deal.
Also, for those of you who didn’t live through 2008, there were plenty of people who assured everyone that everything was OK right until the music stopped.
